中文摘要:采用溶胶-凝胶法,在磁性Fe3O4表面包覆TiO2,制备了一种新型六方晶型纳米TiO2/Fe3O4光催化复合材料。X射线衍射(XRD),透射电镜(TEM)对材料形态结构及包覆情况的分析,显示TiO2包覆在Fe3O4表面,对染料废水光催化降解的模拟研究表明,该复合材料对活性深蓝染料的脱色率达94%,是一种便于回收、可重复使用的高效光催化剂。
外文摘要:A novel magnetic-nanometer TiO2/Fe3O4 photocatalyst composite was prepared.The photoactive TiO2 was deposited onto the surface of magnetic Fe3O4 cores by a sol-gel coating technique.The morphological structure and cladding condition of the photocatalyst particles were characterized by XRD and TEM,TiO2 cladding surface of Fe3O4 was showed.The photocatalysis degradation of dye waste water was simulated,that showed the photocatalyst composite had decoloration of 94% on active deep blue dye.The photocatalyst is easy to recovery,reusable and highly effective.
